问题描述
我正在我的应用程序中打开一个 NestedScrollView，到目前为止它是从屏幕底部打开的.如何从顶部打开它?
我尝试删除以下行:
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"但应用程序崩溃并出现以下错误:
该视图与BottomSheetBehavior没有关联有没有办法从屏幕顶部打开底部工作表?
这是我的活动:
ViewPager mainViewPager;私有BottomSheetBehavior mBottomSheetBehavior;int 切换器 = 1;视图菜单弹出视图；@覆盖protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.workorder_selection_layout_with_fragment);工具栏工具栏 = (工具栏) findViewById(R.id.toolbar);setSupportActionBar(工具栏);..........过滤器按钮 =(按钮)findViewById(R.id.filterButtonMainWorkorderSelection);filterButton.setOnClickListener(new View.OnClickListener() {@覆盖public void onClick(View v) {如果(切换器 == 1){mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);切换器 = 2;} 别的 {mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);切换器 = 1;}}});/////////////////////////////////////////////////////////屁股表/////////////////////////////////////////////////////////////查看bottomSheet = findViewById(R.id.bottom_sheet);mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);}这是我的 xml:

我不确定这是您想要的，但以下链接是 BottomSheetBehavior 的顶级"版本.
包括示例应用的完整代码:https://github.com/ipuris/AndroidTopSheet
将 TopSheetBehavior 类包含到您的项目中，然后您可以通过将 app:layout_behavior 值更改为 TopSheetBehavior 而不是 来使用它>android.support.design.widget.BottomSheetBehavior.
以上代码分叉自 原始存储库，但我修复了一些库依赖项(旧 android.support library -> androidx library) 用于最新版本的 Android.
(也许这个答案对@jernkuan 来说太晚了，但我希望这个答案可以帮助其他开发者.)
I'm opening a NestedScrollView in my app and so far it opens from the bottom of the screen. How do I make it open from the top?
I tried removing the following line:
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
But the app crashes with the following error:
The view is not associated with BottomSheetBehavior
Is there a way to open the bottom sheet from the top of the screen?
Here is my activity:
ViewPager mainViewPager;
private BottomSheetBehavior mBottomSheetBehavior;
int switcher = 1;
View menuPopupView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.workorder_selection_layout_with_fragment);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
...
....
...
filterButton = (Button)
findViewById(R.id.filterButtonMainWorkorderSelection);
filterButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (switcher == 1) {
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
switcher = 2;
} else {
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
switcher = 1;
}
}
});

View bottomSheet = findViewById(R.id.bottom_sheet);
mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
}

解决方案
I'm not sure this is what you want, but the following link is a 'top' version of BottomSheetBehavior.
Full code including example app: https://github.com/ipuris/AndroidTopSheet
Include the TopSheetBehavior class to your project, then you can use it by changing the app:layout_behavior value to TopSheetBehavior instead of android.support.design.widget.BottomSheetBehavior.
Above code is forked from the original repository, but I fixed some library dependencies (old android.support library -> androidx library) for latest version of Android.
(Maybe this answer is too late for @jernkuan, but I hope this answer can be helpful other developers.)
